Abstract
Description
- This application claims the benefit of priority of provisional Patent Application No. 61/941,356, filed on Feb. 18, 2014, the entire contents of which are incorporated herein by reference.
- The instant disclosure relates to replacement of hydraulic hoses. More specifically, this disclosure relates to replacement of hydraulic hoses coupled to a blowout preventer (BOP) located subsea.
- A significant financial loss to companies in the offshore oil drilling industry may be attributed to the amount of time a blowout preventer (BOP) spends disconnected from an offshore well when the BOP is supposed to be connected to the well to allow for safe retrieval of fluids from the well. BOPs are pulled from wells for numerous reasons besides general maintenance of the BOPs. For example, one common reason for pulling a BOP from a well is a faulty hydraulic hose connected to the BOP. Hoses may become faulty for a variety of reasons, such as a leak in the hose or a loosened/bad connection. Because BOPs may have tens, or even hundreds, of hose connections, a BOP may need to be pulled from a well multiple times during scheduled drilling times in order to fix or replace faulty hoses. Therefore, a key to decreasing the financial losses is reducing the number of BOP pulls to fix/replace faulty hoses.
- Reducing the number of BOP pulls to fix/replace faulty hoses may be achieved by replacing, at subsea, the faulty hoses coupled to the BOP as opposed to on an offshore vessel after the BOP has been pulled. According to one embodiment, an apparatus for replacing a first hose coupled to a BOP located subsea may include a first wrench head configured to couple to a hose fitting coupled to the BOP. The apparatus may also include a second wrench head coupled to the first wrench head and configured to couple to a swivel fitting, wherein the swivel fitting couples a first hose to the hose fitting. The apparatus may further include a powering unit coupled to the second wrench head, wherein the powering unit is configured to cause the second wrench head to rotate with respect to the first wrench head, wherein the rotation of the second wrench head causes the swivel fitting to rotate with respect to the hose fitting.
- According to another embodiment, an apparatus for replacing a hose coupled to a BOP located subsea may include a means for coupling to a hose fitting coupled to the BOP and a means for coupling to a swivel fitting, wherein the swivel fitting couples a first hose to the hose fitting, and wherein the means for coupling to the swivel fitting is coupled to the means for coupling to the hose fitting. The apparatus may also include a means for causing the means for coupling to the swivel fitting to rotate with respect to the means for coupling to the hose fitting, wherein the rotation of the means for coupling to the swivel fitting causes the swivel fitting to rotate with respect to the hose fitting, and wherein the means for causing the means for coupling to the swivel fitting to rotate is coupled to the means for coupling to the swivel fitting.
- According to yet another embodiment, a method for replacing a hose coupled to a BOP located subsea may include coupling an electromechanical tool to a hose fitting coupled to the BOP and rotating, with the electromechanical tool, a first swivel fitting with respect to the hose fitting, wherein the first swivel fitting couples a first hose to the hose fitting, and wherein the first swivel fitting is rotated until the first hose is decoupled from the hose fitting. The method may also include coupling, with the electromechanical tool, a second swivel fitting to the hose fitting, wherein the second swivel fitting couples a second hose to the hose fitting. The method may further include rotating, with the electromechanical tool, the second swivel fitting with respect to the hose fitting, wherein the second swivel fitting is rotated until the second hose is securely coupled to the hose fitting.
- The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter that form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims. The novel features that are believed to be characteristic of the invention, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present invention.
- For a more complete understanding of the disclosed system and methods, reference is now made to the following descriptions taken in conjunction with the accompanying drawings.

FIG. 5 is a flow chart diagram illustrating a method for replacing a hose coupled to BOP located subsea according to one embodiment of the disclosure. -
FIG. 1 provides an illustration of an apparatus for replacing a hose coupled to a BOP located subsea according to one embodiment of the disclosure. The apparatus may include afirst wrench head 102 and asecond wrench head 104. Thefirst wrench head 102 may be configured to couple to a hose fitting (not shown) coupled to a BOP (not shown). In some embodiments, thefirst wrench head 102 may include one or more spring loaded ball bearings (not shown) to aid in coupling to the hose fitting. Thesecond wrench head 104 may be coupled to thefirst wrench head 102 in a manner that allows thefirst wrench head 102 to remain in place while thesecond wrench head 104 rotates with respect to thefirst wrench head 102. Thesecond wrench head 104 may be configured to couple to a swivel fitting (not shown). As an example, and not limitation,FIG. 2 provides an illustration of a hose fitting and swivel fitting to which an apparatus for replacing a hose may be coupled according to one embodiment of the disclosure. According to one embodiment, thefirst wrench head 102 andsecond wrench head 104 may couple to the hose fitting 106 and the swivel fitting 108, respectively. In some embodiments, thehose fitting 106 may be coupled to a BOP (not shown), and theswivel fitting 108 may couple ahose 110 to the hose fitting 106. According to one embodiment, the hose and/or swivel fittings may be Joint Industry Council (JIC) standard fittings. - Returning to
FIG. 1 , theapparatus 100 may also include apowering unit 112. Thepowering unit 112 may be coupled to thesecond wrench head 104 and may be configured to cause thesecond wrench head 104 to rotate with respect to thefirst wrench head 102. For example, thepowering unit 112 may include a motor (not shown). The motor may be coupled to adrive gear 114 that may receive energy from the motor. In some embodiments, thedrive gear 114 may be coupled to at least onedrive shaft 116 to transfer motion from thedrive gear 114 to another gear. For example, according to one embodiment, theapparatus 100 may also include at least onespur gear 118 that is driven by thedrive shaft 116 to transmit torque to thesecond wrench head 104. As thedrive gear 114 drives thedrive shaft 116, thedrive shaft 116 may drive thespur gear 118 to transfer motion from thedrive gear 114 to thespur gear 118. According to an embodiment, as thespur gear 118 transmits torque to thesecond wrench head 104, thesecond wrench head 104 may rotate, which may cause the swivel fitting to rotate with respect to the hose fitting. In some embodiments, while the second wrench head 104 and the swivel fitting rotate, thefirst wrench head 102 may remain coupled to the hose fitting and the hose fitting may remain coupled to the BOP such that the first wrench head 102 experiences minimal or no rotation. - In some embodiments, the
apparatus 100 may also include a camera (not shown) that may be positioned on theapparatus 100 such that the viewing area of the camera includes at least thefirst wrench head 102 and thesecond wrench head 104. For example, in one embodiment, the camera may be positioned atlocation 120. In another embodiment, the camera may be positioned atlocation 122. According to an embodiment, theapparatus 100 may be able to be used at water depths up to 3500 meters, and the camera may allow an operator of a remotely operated underwater vehicle (ROV) or a well to remotely view at least thefirst wrench head 102 and thesecond wrench head 104 as theapparatus 100 attempts to remove and/or replace a hose coupled to a subsea electromechanical structure, such as a BOP. - Although the illustration of
FIG. 1 shows that thefirst wrench head 102 is a hex wrench head for coupling to (e.g., receiving) a hex hose fitting, thefirst wrench head 102 may, in general, be adjustable or interchangeable such that thefirst wrench head 102 matches the shape of the hose fitting Likewise, thesecond wrench head 104 may be a hex wrench head as shown inFIG. 1 , but it need not be a hex wrench head, and instead thesecond wrench head 104 may, in general, be adjustable or interchangeable such that thesecond wrench head 104 matches the shape of the swivel fitting coupled to a hose. In general, the inner shape of thefirst wrench head 102 and/or thesecond wrench head 104 may be whatever shape necessary to couple to the hose fitting and the swivel fitting, respectively, without departing from this disclosure in spirit or scope. -
FIG. 3 is a schematic model illustrating a bottom view of theapparatus 100 for replacing a hose coupled to a BOP located subsea according to one embodiment of the disclosure, andFIG. 4 is a schematic model illustrating theapparatus 100 engaged for replacing a hose coupled to a BOP located subsea according to one embodiment of the disclosure. For example,FIG. 4 illustrates theapparatus 100 in position to rotate the swivel fitting to decouple thehose 110 from the hose fitting that is coupled to theBOP 124. Because thesame apparatus 100 may be used to couple a new hose to the hose fitting, in another embodiment,FIG. 4 may illustrate theapparatus 100 in position to rotate the swivel fitting to couple a new hose to the hose fitting that is coupled to theBOP 124. - In view of exemplary systems shown and described herein, methodologies that may be implemented in accordance with the disclosed subject matter will be better appreciated with reference to various functional block diagrams. While, for purposes of simplicity of explanation, methodologies are shown and described as a series of acts/blocks, it is to be understood and appreciated that the claimed subject matter is not limited by the number or order of blocks, as some blocks may occur in different orders and/or at substantially the same time with other blocks from what is depicted and described herein. Moreover, not all illustrated blocks may be required to implement methodologies described herein. It is to be appreciated that functionality associated with blocks may be implemented by the systems disclosed herein or other electromechanical structures without deviating from this disclosure in spirit or scope.

FIG. 5 illustrates amethod 500 for replacing a hose coupled to BOP located subsea according to one embodiment of the disclosure. It is noted that embodiments ofmethod 500 may be implemented with the systems described above with respect to FIGS. 1 and 3-4. For example, embodiments ofmethod 500 may be implemented byapparatus 100. In general, embodiments ofmethod 500 may be implemented by other electromechanical structures without deviating from this disclosure so long as the electromechanical structures, whether directly or indirectly, support the operations as described herein. - Specifically,
method 500 of the illustrated embodiments includes, atblock 502, coupling an electromechanical tool to a hose fitting coupled to a BOP. Atblock 504,method 500 also includes rotating, with the electromechanical tool, a first swivel fitting with respect to the hose fitting, wherein the first swivel fitting couples a first hose to the hose fitting. When the first swivel fitting is being rotated to decouple the first hose, the first swivel fitting may be rotated until the first hose is decoupled from the hose fitting. In some embodiments, at least a first portion of the electromechanical tool remains coupled to the hose fitting while at least a second portion of the electromechanical tool rotates the first swivel fitting. - At
block 506,method 500 includes coupling, with the electromechanical tool, a second swivel fitting to the hose fitting. According to an embodiment, the second swivel fitting may couple a second hose to the hose fitting. For example, with the first hose removed from the hose fitting, a replacement hose may be coupled to the hose fitting. In some embodiments, the electromechanical tool may retrieve the replacement hose from an offshore vessel at the surface after decoupling the first hose from the hose fitting. In another embodiment, the electromechanical tool may be configured to hold the replacement hose while decoupling the first swivel fitting, and therefore the first hose, from the hose fitting. Therefore, according to some embodiments, the electromechanical tool, such as, for example,apparatus 100, may also include a grasping unit configured to hold the second hose (e.g., replacement hose). In yet another embodiment, a second tool may hold the replacement hose in close proximity to the electromechanical tool while the electromechanical tool decouples the first swivel fitting from the hose fitting. -
Method 500, as shown inFIG. 5 , also includes, atblock 508, rotating, with the electromechanical tool, the second swivel fitting with respect to the hose fitting, wherein the second swivel fitting is rotated until the second hose is securely coupled to the hose fitting. According to one embodiment, the electromechanical tool may include a pressure setting that sets the torque value that can be used to secure the second hose to the hose fitting, and the second hose may be securely coupled to the hose fitting when the torque value is reached. In some embodiments, the electromechanical tool may include a torque limiter to avoid over torque, which may cause damage to a fitting. According to an embodiment, the torque value may vary based on the type, size, material, and other characteristics of the fitting, and the pressure setting of the electromechanical tool may be adjusted to account for different torque values. - According to an embodiment, at least a first portion of the electromechanical tool remains coupled to the hose fitting while at least a second portion of the electromechanical tool rotates the second swivel fitting. In some embodiments, the electromechanical tool may include a motor coupled to a plurality of gears and the at least second portion of the electromechanical tool to cause the at least second portion to rotate the first swivel fitting, such as when decoupling the first hose from the hose fitting, or the second swivel fitting, such as when coupling the second hose to the hose fitting.
- According to one embodiment, the electromechanical tool may be remotely operated with an ROV, while in another embodiment, the electromechanical tool may be remotely operated from an offshore vessel, where the electromechanical tool receives instructions/controls from an operator on the offshore vessel. Therefore, in some embodiments, the electromechanical tool may include a camera to remotely view the area that includes at least the hose fitting and either of the first swivel fitting or the second swivel fitting.
